This vacuum insulated, 18/8 stainless steel mug has been thoughtfully designed to make your drinking experience as easy and enjoyable as possible. It’s sturdy enough for any adventure while also preserving the taste and aroma of your beverage to ensure that every sip is perfectly refreshing. A copper-coated double wall construction will preserve your iced tea, cocktail or smoothie at its optimal temperature and ensure that the outer wall of the mug will not sweat. Cold drinks stay cool for 17 hours while hot beverages can last 3 hours before losing their warmth. Helia also features a handy durable glass straw and cleaning brush so you can avoid disposable plastic straws altogether. And you can rest assured that, like all SIGG products, it has been designed with sustainability and food safety as top priority; meaning it’s both recyclable and free of harmful chemicals such as BPA. Choose from Lingonberry (pink), Milky Green or Night Ink (blue). Capacity: 0.45L
